$BUILTIN test
$FUNCTION test_builtin
$SHORT_DOC test [expr]
Exits with a status of 0 (true) or 1 (false) depending on
the evaluation of EXPR Expressions may be unary or binary Unary
expressions are often used to examine the status of a file There
are string operators as well, and numeric comparison operators
File operators:
-a FILE True if file exists
-b FILE True if file is block special
-c FILE True if file is character special
-d FILE True if file is a directory
-e FILE True if file exists
-f FILE True if file exists and is a regular file
-g FILE True if file is set-group-id
-h FILE True if file is a symbolic link
-L FILE True if file is a symbolic link
-k FILE True if file has its `sticky' bit set
-p FILE True if file is a named pipe
-r FILE True if file is readable by you
-s FILE True if file exists and is not empty
-S FILE True if file is a socket
-t FD True if FD is opened on a terminal
-u FILE True if the file is set-user-id
-w FILE True if the file is writable by you
-x FILE True if the file is executable by you
-O FILE True if the file is effectively owned by you
-G FILE True if the file is effectively owned by your group
-N FILE True if the file has been modified since it was last read
FILE1 -nt FILE2 True if file1 is newer than file2 (according to
modification date).
FILE1 -ot FILE2 True if file1 is older than file2
FILE1 -ef FILE2 True if file1 is a hard link to file2
String operators:
-z STRING True if string is empty
-n STRING
STRING True if string is not empty
STRING1 = STRING2
True if the strings are equal
STRING1 != STRING2
True if the strings are not equal
STRING1 < STRING2
True if STRING1 sorts before STRING2 lexicographically
STRING1 > STRING2
True if STRING1 sorts after STRING2 lexicographically
Other operators:
-o OPTION True if the shell option OPTION is enabled
! EXPR True if expr is false
EXPR1 -a EXPR2 True if both expr1 AND expr2 are true
EXPR1 -o EXPR2 True if either expr1 OR expr2 is true
arg1 OP arg2 Arithmetic tests OP is one of -eq, -ne,
-lt, -le, -gt, or -ge
Arithmetic binary operators return true if ARG1 is equal, not-equal,
less-than, less-than-or-equal, greater-than, or greater-than-or-equal
than ARG2
$END
$BUILTIN [
$DOCNAME test_bracket
$FUNCTION test_builtin
$SHORT_DOC [ arg.. ]
This is a synonym for the "test" builtin, but the last
argument must be a literal `]', to match the opening `['.
